Yah, so I get what I deserve I guess.

Yes, as does "halt" and "reboot" and "Ctrl+Alt+Delete". Halt and reboot
say they are doing things then nothing happens. Control returns to that
bash prompt, and you can still Alt+F2 to another TTY.
Ctrl+Alt+Delete says "the system is going down now" then that TTY
becomes unresponsive, but you can Alt+F2 to another TTY.

I get ReiserFS corruption from time to time. I have always assumed that
it was due to rudely killing the system without a clean shutdown --
particuarly if some disk activity was occurring at the time. For
instance sometimes I will get corruption under /var/log, since there is
a lot of activity there. My "big" partition will get some recoverable
corruption from time to time. I always run the latest kernel. It
hasn't happened in a while, but I haven't rudely killed the system much
lately until this USB HD Reiserfs panic issue. I will just "not do
that" as you suggest. I just asked in case anyone knew anything.

Okay, I don't want to get into an argument about this either. I said
"how can I yank a mounted partition" and you said "it's stupid to yank a
mounted partition or even think you should be able to" meanwhile another
guy has in the same timeframe written a script called usbmount that lets
you yank a mounted partition!
But we can move on past that now, I'm not feeling touchy or anything.
What I'm doing now is messing with autofs which has its own problems,
but would probably work for me (it automatically unmounts parts after
disuse for n seconds, but the current version in sid is broken and never
unmounts *anything* (bug #278076). When autofs is working, then I'll
use that and be happy as a tick.
Thanks Ron for the dialog.
